Does Debacterol® Sting?

Does it normally sting this much?

Debacterol®  is a one-time treatment with a tissue denaturant that causes stinging upon contact.  After the initial 5 seconds canker sore pain is generally resolved for good.  Generally, with one quick treatment, pain is resolved for the continued course of a sore.  Even foods that were once excruciating can be consumed.

Is there anything that can help with the stinging?

If the initial stinging sensation of Debacterol®  is difficult to tolerate, numbing the area with a benzocaine product ahead of time can help.
